Please meet some addiction professionals and get some educated experience. I did, and your pronouncements are way off.
Paranoia is just one of the mental side effects from MJ. Some get this one, others get any of several other effects. Varies per person. What is universal is that it is seriously mind altering. While I would like a whole lot more Torah knowledge that I have, I’m otherwise happy with my mental state, and am opposed to anything that will interfere with it. Any such effect is a negative experience for me, and I resist it. Not so for the abuser of a drug (including MJ). The experience of a negative side effect does not deter one from repeating the use. Besides, those with other issues may find the escape into an altered state of mind inviting. And that is not a good situation.
As far as the studies on the psychiatric problems resulting from MJ. they are extensive. Check this out on websites like NIDA (National Institute on Drug Abuse). These studies are not publicized by our liberal media that considers the ills of MJ as benign, just as they so with other ills of society (vehamaivin yovin).
Yes, they had tobacco in Ukraine during the ties of the B”esht. There were many tzaddikim who smoked with all sorts of kavanos. We cannot judge them from our vantage point, since we now have the information about the dangers of smoking which were unknown at those times.
